Hi Just to document this discussion a bit more:

There is a translation from koma-article to scrartcl in the
org-latex-classes, so that is not the problem.

Despite this, there is a repetition, and the clash is because ox-latex
wants ngerman wiith
#+language: de
while Horst wants to use germanb. The clash is between what ox-latex
generates and what Horst tries to add with #+LATEX_HEADER:

Actually, he also needs greek and for that I have recommended to customise
variables so that fontenc is "LGR,T1" and the parameters for babel are
"greek,AUTO", instead of trying to add a #+LATEX_HEADER:
\usepackage[LGR,T1]fontenc, because that also generates a package
option clash.

That is something we might need to explore more, if/when people need/want
to use pdflatex instead of luatex or xelatex.

Once again, yes, because it is mainly a matter of #+language.
I think we need the following
1) more docs on #+language
2) more thought on multilingual documents (#+language: gr,de)
3) more though on documents with multiple font encodings.

Best, /PA
